Display shows L1 or LO and interior temperature is too low; bottles may be over-chilled or freezing.
Low Temperature Alarm / Overcooling
Symptom
Buttons on the control panel do not respond or respond intermittently; temperature cannot be adjusted.
Keypad / Touch Control Failure
Symptom
Chemical or burning plastic smell coming from the wine cooler, especially near the rear.
Overheating Electrical Component or Insulation
Symptom
Condensation or moisture forming on the glass door or around the door frame.
Door Gasket or Ambient Humidity Issue
Symptom
Display is blank or very dim, but the wine cooler still runs and cools.
Display Backlight or UI Power Failure
Symptom
Door gasket is torn, cracked, or not sealing, leading to warm temperatures and condensation.
Door Gasket Failure
Symptom
Ice buildup on the rear interior wall or around the evaporator cover; airflow seems restricted.
Frost or Ice Accumulation on Evaporator
Symptom
Strong musty or moldy odor inside the wine cooler.
Biological Growth Due to Moisture and Poor Airflow
Symptom
Water pooling at the bottom of the wine cooler interior or leaking onto the floor from the front.
Defrost Drain Clog or Condensate Management Failure
Symptom
Wine cooler cycles on and off very frequently (short cycling), with small temperature swings.
Short Cycling / Control Sensitivity Issue
Symptom
Wine cooler door does not close properly or pops open slightly after being shut.
Door Alignment or Hinge Problem
Symptom
Wine cooler emits a high-pitched squealing or chirping noise from inside the cabinet.
Evaporator Fan Bearing Wear or Ice Interference
Symptom
Wine cooler interior light does not turn on when door is opened; display and cooling work normally.
Light Circuit Failure
Symptom
Wine cooler interior light stays on all the time, even with the door closed; cabinet may get warm near the light.
Door Switch or Light Control Failure
Symptom
Wine cooler is too cold; bottles or labels show signs of freezing even at moderate setpoints.
Thermostat or Sensor Calibration Error / Overcooling
Symptom
Wine cooler is unusually warm on the sides or top exterior surfaces.
Condenser Heat Transfer or Door Heater Operation
Symptom
Wine cooler makes a loud rattling or clanking noise when the compressor starts or stops.
Loose Components or Tubing Vibration
Symptom
Wine cooler makes loud humming or buzzing noise from the rear while running.
Compressor or Condenser Fan Noise / Vibration
Symptom
Wine cooler not cooling at all; interior is at room temperature, display appears normal, but no compressor or fan noise.
Compressor Not Running / Control or Start Circuit Failure
Symptom
Wine cooler runs but does not reach set temperature; interior is cool but not cold enough.
Partial Loss of Cooling / Inefficient Sealed System
Symptom
Wine cooler runs continuously without shutting off, yet temperature is near or at setpoint.
Compressor Run-On / Control Relay Stuck
Symptom
Wine cooler vibrates excessively or produces a low-frequency rumble that can be felt through cabinets or floor.
Cabinet Vibration / Installation Issue
